[R] crimtab related question
Dear all,
the dataset documented under ?crimtab was also used in:
@article{TreloarAE1934,
title = {The adequacy of {S}tudent's criterion of
deviations in small sample means},
author = {Treloar, A.E. and Wilder, M.A.},
journal = {The Annals of Mathematical Statistics},
volume = {5},
pages = {324-341},
year = {1934}
}
The following is from page 335 of the above paper:
From the table provided by MacDonell (1902) on
the associated variation of stature (to the nearest inch)
and length of the left middle finger (to the nearest
millimeter) in 3000 British criminals, the measusurements
were transferred to 3000 numbered Denison metal-rim
tags from which the cords has been removed. After
thorough checking and mixing of these circular disks,
samples of 5 tags each were drawn at random until the
supply was exhausted. Unfortunately, three of these
samples were erroneously returned to a receiving box
before being copied, and the records of 597 samples only
are available.
Could someone give me a clue about the kind of device
that was used here? Is it a kind of lottery machine?
I don't understand why three samples were lost. What
is this receiving box?
Thanks for any hint,
Best,

Re: [R] crimtab related question
Hi Jean,
You haven't yet had a reply from an authoratitive source, so here is my
tuppence worth to part of your enquiry.
It's almost certain that the receiving box is a receptacle into which tags
were placed after they had been drawn and the inscribed measurement noted
down. Measurements on three tags were unwittingly not noted before the tags
were transferred to the receiving box. They lay there with a good many
other tags, so the inscribed measurement/tag couldn't be recovered.
I hope this clarifies some points.
Regards,
Mark.

Re: [R] crimtab related question
While on the subject of mechanical methods of statistical research I
can't
resist quoting Doob's (1997) Statistical Science interview:
My system, complicated by my inaccurate typing, led to retyping
material over and over, and for some time I had an electric drill
on my desk, provided with an eraser bit which I used to erase
typing. I rarely used the system of brushing white fluid over a
typed error because I was not patient enough to let the fluid dry
before retyping. Long after my first book was done I discovered the
tape rolls which cover lines of type. As I typed and retyped my
work it became so repugnant to me that I had more and more
difficulty even to look at it to check it. This fact accounts for
many slips that a careful reading would have discovered. I commonly
used a stochastic system of checking, picking a page and then a
place on the page at random and reading a few sentences, in order
to avoid reading it in context and thereby to avoid reading what
was in my mind rather than what I had written. At first I would
catch something at almost every trial, and I would continue until
several trials would yield nothing. I have tried this system on
other authors, betting for example that I would find something to
correct on a randomly chosen printed page of text, and
nonmathematicans suffering under the delusion that mathematics is
errorless would be surprised at how many bets I have won.
The relevance to the present inquiry is confirmed by the misspelling
of Dennison in the Annals reference
quoted below. See, for example:
http://www.amazon.com/Avery-Dennison-Metal-Rim-Tags/dp/B000AN376G
On the substance of Jean's question, Mark's interpretation seems very
plausible.
Thanks to Jean and to Martin Maechler for adding this dataset to R.
